Retractable protective respiratory mask

ABSTRACT

A retractable protective respiratory mask including disposable filters, which protects the respiratory system, covering the nose and mouth during inhalation while breathing in an atmosphere polluted by different agents, such as infectious, virulent, or pathogenic agents, or other toxic substances. The mask also protects non-infected persons from persons infected with a virus, as saliva and sputum expelled when coughing, breathing-out, and/or talking can be deposited inside the mask. The mask can include a collection-container filter, allowing a viral-infected wearer to breathe in a polluted atmosphere, to talk, to cough, to sneeze and/or to deposit saliva and sputum. The mask can be used as any other type of filter mask and/or disposable environmental air mask for industry in general, and also providing protection in rarefied natural atmospheres. The mask can be used as a container or packaging for drugs administered by means of bronchial airways, or as medical or rescue masks.

PRIOR ART OF THE INVENTION

It is now well known that environmental pollution levels (smog), which are affecting the entire planet, as evidenced in all the large cities such as Tokyo, New York, Peking, Mexico City, Los Angeles, as well as the evolution of different virus, that have created resistance to medications and treatments, mutating, for example, the influenzas, its level of transformation has caused, viruses that exclusively affected animals to mutate and infect man, as is the case of the influenzas A, H1N1. Due to their highly contagious quality, this virus is transmitted through the remnants of saliva expulsed and which travel through the environment, when one talks, coughs, sneezes, and breathes, as well as by saliva and sputum cast onto the floor. Nowadays, viruses survive between 48 and 72 hours on smooth surfaces such as hands, handles, railings, floors, as well as tissues and fabrics. It also it is spread by talking, shaking hands or kissing. Although these viruses have claimed many lives throughout history, and today we are threatened by large-scale pandemics of multiple virus strains. This is due to not having the option to easily access effective drugs and by not consistently following the recommendations given by the authorities so that it does not spread. To avoid passing a contagious disease from person to person, several recommendations have been given, such as covering your nose and mouth with a disposable handkerchief when coughing or sneezing and not doing so directly into your hand. Not greeting others with a kiss or by shaking hands. Always wash your hands with soap and water after sneezing and after picking up things that other people have touched such as railings and bus handrails, as well as having to handle used disposable handkerchiefs, by putting them inside plastic bags and closing them before throwing them in the garbage. Do not spit on the floor, because when an uninfected person steps on this, they transport it to their homes on their shoes. Symptoms of these influenzas and in particular those of Influenza A and H1N1 and the like, most characteristics are: Persistent, intense cough, sore, burning throat, sneezing, difficulty breathing, severe headaches, high fever, and nasal congestion. So that coughing, talking, sneezing, breathing, and spitting from infected persons do not infect other people, it is recommended that non-infected people wear a traditional face mask with a filter, which fits over the ears or the head. It is well known that the existence of protective masks with air filters to protect the user from infections in the environment, as in the U.S. Pat. No. 5,468,8566 where a mask for filtering air inhaled and/or exhaled from the mouth and nose by creating an airtight seal. Different elements have been designed. For example, surgical masks, face masks, masks for breathing fresh air in polluted environments which purify the air exhaled through the mouth and nose, when coughing and sneezing in the cases of persons infected with flu, colds and other illnesses. However, they are not suitable for the accumulation of fluids. The elements used, to protect the respiratory system, covering the nose and mouth during inhalations, when breathing atmospheres contaminated by viruses from ill persons through contagious agents in the air are not sufficiently efficient to stop the propagation of the viruses such as the influenza viruses because generally, masks covering the mouth and nose are designed with a standard and rigid form as well as for the different types of noses, making it possible for air to be breathed through these leaks. The same is true for face masks that have a wire on its interior. They do not allow an ergonomic fit over the nose from its apex to the half curve of the cheekbones.

OBJECT OF THE INVENTION

The principal purpose of the manufacture of the retractable protective respiratory mask device with air filter collectors, disinfectants, is to be able to have it on hand whenever the health of our respiratory system is threatened to be able to rely on an item that is simple, safe, effective and portable that makes it possible at any time during our daily life to immediately respond to situations such as having to go among vehicles that are contaminated, if we must use an elevator where there is someone with the symptoms of a severe infection, to be thus able to use it quickly and effectively in risky everyday situations where we become involved in exposures to infection from environments contaminated by toxic agents by having an ergonomic fit between the nose and mouth, which is retractable, that provides a 100% airtight seal between the environment and the mouth and nose and the respiratory system allowing entry of only filtered fresh air to the respiratory system and also makes it so that only clean filtered air will leave the respiratory system of people infected by some type of a virus and enter into the environment, to both protect a person breathing in areas polluted by some toxic agent, pathogen and/or influenza viruses, and vice versa for use by persons infected with a virus, and thus not allow it to spread.

Additionally this invention exists in the need to create a retractable protective respiratory mask device which allows persons infected with a virus or respiratory disease to be able to deposit the sputum and saliva within its absorbent filter bag with an elastic band several times before having to replace it with a new one. Another no less important object of this retractable mask is that it is designed so that the mask is only open at the time of use. Remaining permanently closed and secured, with no problem that the interior may become contaminated if it is used as a protective filter for the respiratory system, nor does it allow the escape of any infectious bacteria if used by persons infected by viruses or respiratory diseases when it is in repose or closed. Because this mask is retractable, its doors as well as the expandable filter cover, causes its size to be, while the doors and the expandable filter cap are closed, no larger than a cell phone, only a quarter of the total bulk volume of its size, when it is open, making it lightweight, comfortable, ergonomic, lightweight, easy to carry, due to being manufactured in thin, resistant plastic, this mask may be transported in several forms, from inside a pocket to hanging by a cord around the neck.

This invention fulfills these needs and has other related advantages such as that to be used as a traditional filter mask for ambient air and/or container and/or packaging for medicines for human use with application in the pulmonary bronchi and/or as a mask for different medical, safety or rescue equipment, only when the safety is applied is it in the open position. The novel characteristics which are considered as the source of the invention are set forth in detail in the appended claims, and will be explained in the detailed description together with its further advantages. Your understanding will be better with the clear description and its preferred embodiment, with due reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

This invention concerns a device, a retractable protective respiratory mask that has doors which open and close, which have grooves over its doors to hold the filter bag or sleeve through the elastic bands that fit into the grooves in the doors that open making a perfect seal between the mouth and nose against the environment possible and allowing for the deposit of saliva and sputum, expulsed when talking and/or sneezing, and/or coughing, and/or spitting, characterized in that this device possesses two doors in a curved shape which open in the same manner as the expandable filter cover by the action of the mechanical and/or electric, and/or hydraulic, and/or pneumatic systems, and closes the doors and at the same time contracts the cover of the expandable filter, through spring action, when pressure is not applied with the hand. Furthermore, when it is closed, its size is only one third of the total volume of its size when it is open, making it lightweight, comfortable, ergonomic, light and very easy to carry. These doors in a curved shape have grooves where the elastic bands surrounding the filter bag are connected, permitting it to complete, between the corners of the two open doors, a pear shape when they are open, making it possible to conform itself around the mouth and nose in an airtight manner, as well as when it is removed and it automatically closes by the spring action that contract when there is no pressure applied by hand on the sealing systems. It also has a safety which is a pin that locks the mechanisms and makes it possible to leave the retractable protective respiratory mask device open without needing to continue squeezing the sealer and at the same time making it possible to lock the doors so that they cannot open once closed. More in particular, this invention concerns a collar, that while it is not used, functions as any other mask to filter the air that we breathe from the environment. FIG. 7, shows the simultaneous aperture mechanism of the doors 2, of the retractable protective respiratory mask that pivots over points 3, through action of the rod 5, located between points 7, from the lateral parts 8, of the doors 2, which are those that open or close them simultaneously.
